This article introduces the principle, design ideas and methods of DC current source. The whole system uses MSP430 microcontroller as the controller to control the current sharing, and uses the switching power supply chip LM2576 as the power supply chip. The output of the power supply voltage is controlled by an independent keyboard, and the operation is convenient and simple. The two power supplies can automatically share the current when the external load changes. The whole system has the characteristics of simple circuit, large output voltage range, high precision, stability and reliability, and has overcurrent protection and automatic recovery functions, which meets the requirements of the topic very well.
